Well managed to get my head unit working (dam new vw stereo's) and changer in place.
Going for a stealth/standard look but happy with the results.

Head unit and changer look like they were there from the factory. Managed to get a lead that connects into the back of the stereo that comes out as 4x RCA's and a remote on as well as keeping the standard speaker outputs.
Close up of changer. Still needs tidying up but it's getting there.
